FRUIT JAR CLOSURE Filed July 15, 1936 N 6607296 WHz'ZZih Jn SUM mm;

Patented Sept. 13, 1938 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to a closure means for fruit jars or other receptacles and it generally aims to provide a construction which avoids the use of screw threads and may be readily applied and released with effective pressure so. that the closure will be sealed air tight.

More specifically, it aims to provide a closure means for engagement with a cap, consisting of an L-shaped bail and an arm pivoted thereto,

said arm and the arm of the bail being engageable in lugs on the jar so that the device may thereafter be operated to tightly clamp the closure and its gasket in place.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:

Figure l is a view of a jar equipped with my improvements;

Figure 2 is a plan view of the parts of Figure 1;

Figure 3 is a substantially central vertical sectional view taken on the plane of line 33 of Figure 2, and

Figure 4 is a detail perspective View of the closure-securing parts.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, the improvements have been shown as applied to a fruit jar as at Ill, usually being of glass. This disclosure is to be taken as conventional since the improvements may be applied to any desire-d receptacle. The upper portion of the fruit jar is reduced in diameter as at H and at diametrically opposite points, at the shoulder thus formed, lugs or ears I2 extend outwardly therefrom, the same having openings l3 therethrough. The mouth of the jar is covered by a metallic or other cap or closure l4 and an elastic sealing gasket I5 is preferably interposed between said cap and the upper edge of the jar.

In order to hermetically seal the cap to the jar or equivalent, an L-shaped bail is provided at l6 having a cross arm I! and a depending side arm I 8 rigid therewith. The bail is made of resilient wire and at the free end of the arm ll, an eyelet I9 is formed in which a depending arm 20 is pivotally connected by means of an eyelet 2|. Each of the side arms l8 and 20 have angularly disposed lugs or projections 22 and 23 extending therefrom.

In the closing of the jar or receptacle, after application of the gasket l5 and cap M, the bail I6 is applied as shown in Figures 1, 2 and 3 with lug 22 entering the opening 13 of the adjacent ear I 2 and with the bar I! disposed across the top of the cap 14. Thereupon, the side arm 20, which moves on the longitudinal axis of the arm I1, is rocked so as to engage the lug 23 in the 5 adjacent opening I 3. The parts of bail l6 and arm 20 are so proportioned that the closing or engagement of side arm 20 at 23 with an opening l3, depresses the cap l4 and gasket [5 and secures them in such depressed position, thereby 10 hermetically sealing the jar or container. In order to release the cap, it is simply necessary to initially move the side arm 20 in the reverse direction to disengage the lug 23 from adjacent opening I3, following which, the bail I! may be 15 readily detached.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my.invention:- 20

1. In combination with a jar having openings on opposite sides thereof, said jar being adapted to be closed by a cap and an interposed gasket, a bail disposable across the cap having a depending arm anchored in one of said openings, and a side 5 arm pivoted to one end of the bail and movable in a plane at a right angle to the longitudinal axis of the bail and engageable in the other opening, said bail being removable and each arm being detachably engageable in either opening. 30

2. In combination with a jar having openings at opposite sides thereof, said jar being adapted for closing by a cap and an interposed gasket, I an L-shaped bail having a portion extending across the cap and a depending side arm, said 35 side arm having a lug engaged in one of the openings, a side armv pivoted to the free end of said portion and movable in a plane at a right angle to the longitudinal axis of said portion, the last mentioned side arm having a lug engageable 40 in the other opening, said bail being removable andheach arm being detachably engageable in either opening.

3. In combination with a jar having openings at opposite sides thereof, said jar being adapted 45 for closing by a cap and an interposed gasket, an L-shaped bail having a portion extending across the cap and a depending side arm, said side arm having a lug engaged in one of the openings, a side arm pivoted to the free end of 50 said portion and movable in a plane at a right angle to the longitudinal axis of said portion, the last mentioned side arm having a lug engageable in the other opening, said portion and last mentioned side arm having interengaged eyelets 55 efiecting their pivotal connection, said bail being removable and each arm being detachably engageable in either opening.

4. A securing device for a cap engaging a container, the device comprising an L-shaped bail providing a portion to engage the cap and a depending arm, a, lug extending from the free end of the arm for engagement with an opening of the jar, a side arm pivotally connected to the free end of said portion and movable in a'plane at right angle to the longitudinal axis of said portion, the second mentioned side arm having a lug engageable with an opening of a jar, said bail being removable and each arm being detachably engageable in either opening,
